Development of initial idea

My tutors advised me on how my initial design, shown below was focused too much on the actual bed rather than the enclosure, which was the main focus. They also told me that i should further develop my idea so that it becomes more private, and further emphasise on the "lushness" and "warmth" which were the characteristics I needed in my design.

This was when I started playing around with the idea of rolls/folds of rugs that could make the walls more interesting with a warmer feel to it too. I leaned towards a basic cuboid shaped structure with a roof/cover, until i realised it would feel too much like sleeping in a coffin, triggering claustrophobia in most of us.
